Donald Duck & Co #1/1967

In "Gøy i Alaska," Scrooge McDuck’s presence in a magazine story stirs memories in Soapy Slick, the old Alaskan money lender, who recalls a long-ignored IOU from 1898—accruing 100 percent interest monthly, compounded forever. With Scrooge carrying the receipt to Alaska for a showdown, Soapy is on the same plane, and a sudden struggle sends the flight bag tumbling through a window, landing near a rushing river.
